<INDENT_NAME> is common indent file without '.vim' suffix.
<PATH> is your path of project.

If exists <DEFAULT_INDENT_NAME>, then <DEFAULT_INDENT_NAME>.vim file is
default indent file for this filetype.

For example:
[cpp:shetukhin]
google = $HOME/work/pyctpp2

[c]
linux = $HOME/work/kernels/
gnu = $HOME/work/hurd

2. Create `~/.vim/csindent/<FILETYPE_NAME>/<INDENT_NAME>.vim'
(instead of `~/.vim/csindent` you can use any path from 'runtimepath').
For example:
~/.vim/csindent/cpp/shetukhin.vim
~/.vim/csindent/cpp/google.vim
~/.vim/csindent/c/linux.vim
~/.vim/csindent/c/gnu.vim

Note 1: This script is compatible with `filetype indent`.
See `:help filetype`.

Note 2: You can use more informative status line using CodingStyleIndent().
For example:
set statusline=%<%f%h%m%r%=style=%{CodingStyleIndent()}
\ %15(L%l,C%c%V%)\ %3P
